To invert a high resolution impedance section or seismic section, the earth model must be finely parameterized with large number of parameters. But the conventional global optimization algorithms often lose their effectiveness and advantages when applied to high‐dimensional and complex problems. CCDE is effective and robust for high‐dimensional waveform inversion. It decomposes the high‐dimensional model into some subcomponents. Then another novel feature of CCDE is that, it introduces a local fitness function for each subcomponent, and a new mutation operator is designed to guide the mutation direction of each subcomponent with the corresponding local fitness value. Compare with the commonly used resolution‐enhancement methods, our method can remove internal multiples and needs no assumptions for the wavelet and earth model.Permalink: https://doi.org/10.1190/1.3513032FiguresReferencesRelatedDetailsCited ByAssisted History Matching Using Pattern Recognition Technology3 March 2015Waveform inversion of cross‐well data with cooperative coevolutionary differential evolution algorithmChao Wang, Jinghuai Gao, Huiqun Yang, Wei Zhao, and Zhenyu Zhu8 August 2011 SEG Technical Program Expanded Abstracts 2010ISSN (print):1052-3812 ISSN (online):1949-4645Copyright: 2010 Pages: 4453 publication data© 2010 Copyright © 2010 Society of Exploration GeophysicistsPublisher:Society of Exploration Geophysicists HistoryPublished: 21 Oct 2010 CITATION INFORMATION Chao Wang, Jinghuai Gao, and Bin Weng, (2010), "Enhancing resolution of seismic data based on waveform inversion with cooperative coevolutionary differential evolution algorithm," SEG Technical Program Expanded Abstracts : 1075-1079. https://doi.org/10.1190/1.3513032 Plain-Language Summary PDF DownloadLoading ...
